Excessive incidence of various cancers is a challenging feature of the hereditary-non-polyposis-colorectal-cancer (HNPCC) syndrome. This study estimated the cancer incidences in HNPCC compared with the general population. Individuals in a cohort of 1763 members of 50 genetically diagnosed families w

β¦ Synopsis
Hereditary nonpolyposis colorectal cancer (HNPCC) is a common autosomal dominant disease caused by germline mutations in DNA mismatch repair genes. The mutational spectrum in these genes appears to be diverse, in both the distribution and the nature of the mutations. However, most described mutations generate a premature stop codon and ultimately result in the synthesis of a truncated protein. We have employed an in vitro transcription/translation assay to identify germline mutations in DNA mismatch repair genes from patients suspected of belonging to HNPCC kindreds. Our results suggest that this approach will be highly effective in identifying mutations in these patients and may lead to a reliable diagnostic test for the pre-symptomatic identification of HNPCC.

Fourteen Italian families affected with hereditary nonpolyposis colorectal cancer (HNPCC) were screened for germline mutations at three DNA mismatch repair (MMR) genes, MSH2, MLH1, and GTBP, by using a combination of different methods that included an in vitro synthesized protein assay, single-stran
## Abstract Germline mutations in DNA mismatch repair genes underlie one of the most common hereditary cancer predisposition syndromes known in humans, hereditary nonpolyposis colorectal cancer (HNPCC). Defects of the DNA mismatch repair system are also prevalent in sporadic colorectal cancers. The
Using different molecular techniques, DNA has been shown to be present in plasma of patients with several types of tumors. Mutations of TP53 are the most common genetic changes in human cancers. We investigated the presence of TP53 gene mutations in plasma DNA of breast and small cell lung cancer pa
Germline alterations in human DNA mismatch repair genes are associated with hereditary nonpolyposis colorectal cancer (HNPCC). Mutation analysis of the genes reveals carriers with a high risk of colorectal cancer, who will benefit from surveillance. We wanted to find the best predictive parameter of
Hereditary nonpolyposis colorectal cancer (HNPCC) is frequently associated with inherited mutation in one of four DNA mismatch repair genes. Somatic mutations in the same genes are also found in a subset of sporadic colorectal cancers. A defect in DNA mismatch repair results in an RER (replication e
